Recommendations based on scientific evidence and principles are presented as best practices for safety duplication of crop germplasm. Information on the principles and best practices for safety duplication are spread through the literature. Seeds which are duplicates from other collections can usually be retrieved from those collections and do not require safety duplication unless there is doubt about their security in the other collection. Safety duplication is done for all original seeds collected by the genebank or only held by the genebank. The germplasm is not touched without permission from the depositor and is only returned on request when the original collection is lost or destroyed. It is the depositor’s responsibility to ensure that the deposited material is of high quality, to monitor seed viability over time and to use their own base collection to regenerate the collections when they begin to lose viability. This means that the repository genebank has no entitlement to the use and distribution of the germplasm. Safety duplication is generally under a ‘black-box’ approach. The location is chosen to minimize possible risks and provides the best possible storage facilities. Safety duplicates include both the duplication of material and its related information, and are deposited in a base collection at a different location, usually in another country. The safety duplicates are genetically identical to the base collection and are referred to as the secondary most original sample (Engels and Visser, 2003). This is the duplication of a genetically identical sub-sample of the accession to mitigate the risk of its partial or total loss caused by natural or man-made catastrophes. ![]() Cantrell) Bioversity International/ILRI, Addis Ababa, Ethiopia (Alexandra Jorge) including information extracted from: Rao NK, Hanson J, Dulloo ME, Ghosh K, Nowel D and Larinde M. ![]() (0.1 MB)Ĭontact person for Safety duplication: Jean Hanson, ILRI, EthiopiaĬontributors to this page: CIP, Lima, Peru (David Tay, Ana Panta, Catherine Espinosa) IFPRI, Washington (Daniela Horna) ILRI, Addis Ababa, Ethiopia (Jean Hanson) independent consultant (Juvy B.
